My two biggest wishes as a hardcore PHP programmer:

1. Support finally. It's a big mess to fictionally get around this through flags or similar means.
2. I would LOVE to see support on C#'s syntax for getters and setters. When you have lots of getters and setters a simple syntax such as C#'s is a great performance booster instead of doing it the Java way and writing getter and setter methods. Magic methods are awesome in cases where you want to create members dynamically (for instance, if you want to give a template renderer some variables to use), but are no good for normal properties on which you would like the IDE to autocomplete, know their types, and so on. this would help make code smaller and still as readable and easy to use.
